    Hello, I'm tiling our bathroom and I plan to fit an electric radiator once the wall is tiled so I need to put a cable or conduit in the wall ready. How deep should this cable be in to the wall?
    Many thanks

    As long as its in the permitted wiring routes (straight up or across from an accessory box or within 6" of a corner or the top of a wall) then there is no minimum depth other than what is needed to conceal it without it smiling through the surface, normal practice is to allow at least 3mm of plaster skim above it, but if you are tiling then argueably the conduit could be fush with surface of wall and then just tile over (if you ever took tiles off though, you'd have to skim wall). You must not chase more than 1/6 of wall thickness horizonally, or 1/3 vertically as any more could affect wall structure.

    Are you aware of bothroom zoning in respect to baths and shower enclosures?
